In the construction of a chimney top of this kind no flashing is used to prevent water from running down the sides of the chimney to the interior of. the house, for the reason that the slag or other character of roof can be turned up under the projecting ledge 7, and in this way protecting the chimney below the roofQ However flashing can be used if desired. v

Suitable cable braces as identified at 17 may be used in the openings 11 if desired, for the purpose of additional'bracing the chimney top in'pos'ition. 1' The invention having been set forth, what is claimed is:

1. In a chimney and top structure therefor, a chimney extension protruding above a roof, a terra cotta chimney flue lining extending a substantial distance'down into the chimney and a substantial distance above the chimney brick work, a chimney top of terracotta having a flue the lower end of which receives the substantial lengthof extension of the terra cotta flue lining of the chimney, a secure plastic bonding material between the base portion of the chimney, topaiid the brick work of the chimney eiitensi'on and between the terra cotta flue exterisioii aiidthe. interior passage of the chimney top to hold the chimney top and the chimney terra cottaflue'lifiing elements together to insure a bonding joint, the base portion of the teria chtta chimney top having a marginal projec'ting ledge, which overlies and extends beyond end of the chimney top and in turn adapted to be connected to the roof to retain the chimney top section in place. 7

2. In a chimney and top structure therefor, a chimney extension protruding above a roof, a terra cotta chimney flue lining extending a substantial distance down into the chimney and a substantial distance above the chimney brick work, a chimney top of terra cotta having a flue the lower end of which receives the substantial length of extension of the terra cotta flue lining of the chimney, a secure plastic bonding material between ,the base portion of the chimney top and the brickwork of the chimney extension and between the terra cotta flue ex:
